Important Safety Information 21Using Your Network Extender Near OtherElectronic DevicesMost modern electronic equipment is shielded from radiofrequency (RF) signals. However, RF signals from your NetworkExtender may affect inadequately shielded electronic equipment.Conversely, ensure the unit is placed at least 2 feet away fromproducts which generate electromagnetic radiation, such as acomputer monitor or microwave oven.Note: For the best care of your Network Extender, ensure that only authorizedpersonnel service your device. Failure to do so may be dangerous andvoid your warranty. Consult the manufacturer of any personal medicaldevices, such as pacemakers and hearing aids, to determine if theyare adequately shielded from external RF signals.Radio Frequency (RF) EnergyUnderstanding How Your Network Extender OperatesYour Network Extender functions as a radio transmitter andreceiver. When it is turned on, it receives and transmits radiofrequency (RF) signals. When you use your Network Extender, thesystem handling your call controls the power level.This power can range from 10 microwatt to 30 milliwatts.Knowing Radio Frequency SafetyThe design of your Network Extender complies with updatedNCRP standards described below:In 1991–92, the Institute of Electrical and Electronics Engineers(IEEE) and the American National Standards Institute (ANSI) joinedin updating ANSI’s 1982 standard for safety levels with respect tohuman exposure to RF signals. More than 120 scientists,engineers and physicians from universities, government healthagencies and industries developed this updated standard afterreviewing the available body of research.In 1993, the Federal Communications Commission (FCC) adoptedthis updated standard in a regulation. In August 1996, the FCCadopted a hybrid standard consisting of the existing ANSI/IEEEstandard and the guidelines published by the National Council ofRadiation Protection and Measurements (NCRP).For more information about RF exposure, visit the FCC Web siteat www.fcc.gov.
